The Engineer’s Guide to Writing Meaningful Code Comments

,

In most cases, you aren’t the only person working on the same project or codebase. That means that other people get to read your code and have to understand it. That’s also true for the code comments you leave behind. Developers often write ‘quick and dirty’ comments without much context, leaving other developers clueless about what you’re trying to say. It’s a bad practice that creates only more confusion than clarifies things.

So, yes – you should be bothered with writing meaningful code comments to help other developers. A code comment that describes the function, the reasoning behind the function, and its input and output will speed up the learning process of other developers. Especially for junior developers, this information comes in handy when learning the code.

No-Code:  »It’s a Trap! »

,
Gartner predicts that by 2023, over 50% of medium to large enterprises will have adopted a Low-code/No-code application as part of their platform development.
The proliferation of Low-code/No-code tooling can be partially attributed to the COVID-19 pandemic, which has put pressure on businesses around the world to rapidly implement digital solutions. However, adoption of these tools — while indeed accelerated by the pandemic — would have occurred either way.
Even before the pandemic, the largest, richest companies had already formed an oligopsony around the best tech talent and most advanced development tools. Low-Code/No-code, therefore, is an attractive solution for small and mid-sized organizations to level the playing field, and it does so by giving these smaller players the power to do more with their existing resources.
While these benefits are often realized in the short term, the long-term effect of these tools is often shockingly different. The promise of faster and cheaper delivery is the catch — or lure — inside this organizational mousetrap, whereas backlogs, vendor contracts, technical debts, and constant updates are the hammer.
So, what exactly is the No-Code trap, and how can we avoid it?

What is a No-Code Tool?

First, let’s make sure we clear up any confusion regarding naming. So far I have referred Low-Code and No-Code as if they were one term. It’s certainly easy to confuse them — even large analyst firms seem to have a hard time differentiating between the two — and in the broader context of this article, both can lead to the same set of development pitfalls.
Under the magnifying glass, however, there are lots of small details and capabilities that differentiate Low-code and No-code solutions. Most of them aren’t apparent at the UI level, leading to much of the confusion between where the two come from.
In this section, I will spend a little bit of time exploring the important differences between those two, but only to show that when it comes to the central premise of this article they are virtually equivalent.

Low-Code vs. No-Code Tools

The goal behind Low-Code is to minimize the amount of coding necessary for complex tasks through a visual interface (such as Drag ‘N’ Drop) that integrates existing blocks of code into a workflow.
Skilled professionals have the potential to work smarter and faster with Low-Code tools because repetitive coding or duplicating work is streamlined. Through this, they can spend less time on the 80% of work that builds the foundation and focuses more on optimizing the 20% that makes it different. It, therefore, takes on the role of an entry-level employee doing the grunt work for more senior developers/engineers.
No-Code has a very similar look and feel to Low-Code, but is different in one very important dimension. Where Low-Code is meant to optimize the productivity of developers or engineers that already know how to code (even if just a little), No-Code is built for business and product managers that may not know any actual programming languages. It is meant to equip non-technical workers with the tools they need to create applications without formal development training.
No-Code applications need to be self-contained and everything the No-Code vendor thinks the user may need is already built into the tool.
As a result, No-Code applications create a lot of restrictions for the long-term in exchange for quick results in the short-term. This is a great example of a ‘deliberate-prudent’ scenario in the context of the Technical Debt Quadrant, but more on this later.

Advantages of No-Code Solutions

The appeal of both Low-Code and No-Code is pretty obvious. By removing code organizations can remove those that write it — developers — because they are expensive, in short supply, and fundamentally don’t produce things quickly.
The benefits of these two forms of applications in their best forms can be pretty substantial:
  • Resources: Human Capital is becoming increasingly scarce — and therefore expensive. This can stop a lot of ambitious projects dead in their tracks. Low-Code and No-Code tools minimize the amount of specialized technical skills needed to get an application of the ground, which means things can get done more quickly and at a lower cost.
  • Low Risk/High ROI: Security processes, data integrations, and cross-platform support are all built into Low-Code and No-Code tools, meaning less risk and more time to focus on your business goals.
  • Moving to Production: Similarly, for both types of tools a single click is all it takes to send or deploy a model or application you built to production.
Looking at these advantages, it is no wonder that both Low-Code and No-Code have been taking industries by storm recently. While being distinctly different in terms of users, they serve the same goal — that is to say, faster, safer and cheaper deployment. Given these similarities, both terms will be grouped together under the ‘No-Code’ term for the rest of this article unless otherwise specified.

List of No-Code Data Tools

So far, we have covered the applications of No-Code in a very general way, but for the rest of this article, I would like to focus on data modeling. No-Code tools are prevalent in software development, but have also, in particular, started to take hold in this space, and some applications even claim to be an alternative to SQL and other querying languages (crazy, right?!). My reasons for focusing on this are two-fold: 
Firstly, there is a lot of existing analysis around this problem for software development and very little for data modeling. Secondly, this is also the area in which I have the most expertise.
Now let’s take a look at some of the vendors that provide No-Code solutions in this space. These in no way constitute a complete list and are, for the most part, not exclusively built for data modeling. 

1. No-Code Data Modeling in Power BI

Power BI was created by Microsoft and aims to provide interactive visualizations and business intelligence capabilities to all types of business users. Their simple interface is meant to allow end-users to create their own reports and dashboards through a number of features, including data mapping, transformation, and visualization through dashboards. Power BI does support some R coding capabilities for visualization, but when it comes to data modeling, it is a true No-Code tool.

2. Alteryx as a Low-Code Alternative

Alteryx is meant to make advanced analytics accessible to any data worker. To achieve this, it offers several data analytics solutions. Alteryx specializes in self-service analytics with an intuitive UI. Their offerings can be used as Extract, Transform, Load (ETL) Tools within their own framework. Alteryx allows data workers to organize their data pipelines through their custom features and SQL code blocks. As such, they are easily identified as a Low-Code solution.

3. Is Tableau a No-Code Data Modeling Solution?

Tableau is a visual analytics platform and a direct competitor to Power BI. They were recently acquired by Salesforce which is now hoping to ‘transform the way we use data to solve problems—empowering people and organizations to make the most of their data.’ It is also a pretty obvious No-Code platform that is supposed to appeal to all types of end-users. As of now, it offers fewer tools for data modeling than Power BI, but that is likely to change in the future.

4. Looker is a No-Code Alternative to SQL

Looker is a business intelligence software and big data analytics platform that promises to help you explore, analyze, and share real-time business analytics easily. Very much in line with Tableau and Power BI, it aims to make non-technical end-users proficient in a variety of data tasks such as transformation, modeling, and visualization.

You might be wondering why I am including so many BI/Visualization platforms when talking about potential alternatives to SQL. After all, these tools are only set up to address an organization’s reporting needs, which constitute only one of the use cases for data queries and SQL. This is certainly a valid point, so allow me to clarify my reasoning a bit more.

While it is true that reporting is only one of many potential uses for SQL, it is nevertheless an extremely important one. There is a good reason why there are so many No-Code BI tools in the market—to address heightening demand from enterprises around the world — and therefore, it is worth taking a closer look at their almost inevitable shortcomings.

Project Lambda

,

Project Lambda is an effort to bring Java into the world of functional programming. 

Lambda is a function without a name. It is an implementation of functional interfaces. A functional interface is an interface that has only a single custom abstract method that isn’t inherited from the object class. In Java, interfaces such as Runnable, Comparable, and many others are the example of Functional Interfaces. It defines an anonymous implementation for one-time use and significantly streamlines your code.

What Lies Beneath Hard Work: Code Churn

,

Organizations are continuously looking for ways to track, measure, and evaluate developer workflows. Done effectively, this creates the means to improve performance and code quality, reduce time to market and increase profits. But it’s not always easy to measure efficiency. What may first appear to be evidence of a team’s hard work may be an indication of the bigger challenges and inefficiencies of code churn.

What Is Code Churn?

Code churn is a measure or indication of how often a file changes. It typically refers to how often a developer throws out code (such as a function, file, or class) within the first 2-3 weeks of writing.

5 Web Design Trends and Ideas for 2021

,

One of the few bright spots in 2020 has been the creativity companies and individuals alike have exhibited in dealing with what, at times, seemed to be overwhelming problems.

The world of web design was no different. Designers and agencies had to adapt and implement new color schemes or design new shopping experiences, which made some of the previous design trends not fit for the current design problems.

We’ll take a look at these newest design trends and the rationale behind them. As we do so, we’ll also take a look at some of BeTheme’s 600+ pre-built sites that have already put them to good use.

1. Comforting Color Palettes Lighten the Load

In years past, bolder color schemes were one of the hallmarks of web design trends. Their purpose was to quickly engage a visitor and prompt him or her to respond emotionally.

Given all the drama and turmoil we were subjected to through most of 2020, we’ve come to welcome the use of toned-down colors in marketing instead of the bolder, brasher, and more “in-your-face” color schemes. 

Bellroy’s website puts toned-down colors to good use. This company’s product line of wallets, bags, and the like, are designed to keep people’s belongings organized, safe, and secure. A wild color scheme simply wouldn’t be fitting.

How, then, are brightly-colored products dealt with? Thanks to judicious uses of white space and background photos, this website still emphasizes a toned-down color palette.

The BeSpa pre-built website is another example of a color scheme that almost immediately puts the mind at ease.

Calm and soothing? Yes.

Boring? Definitely not.

Comfort and security are the emotional drivers in this example.

2. Seamlessly Intermingle and Balance Physical and Digital Imagery

People confined to their homes because of Covid-based restrictions spent many more hours looking at their screens in 2020. Online programming began to take on the appearance of a reality show that blurred the boundaries between the real and the digital.

Whereas web designers tended in the past to rely on either photos or illustrations in their designs, these same designers have started to integrate these blurring effects into their designs, with results that range from amusing and quirky to highly informative.

Check out this example from fashion designer Constance Burke: 

It’s not every day you see real models wearing hand-drawn fashion sketches. But it’s just one example of how the physical can be blended with the digital.

The BeSki pre-built site does the same blending of the two, but in a totally different way:

The sections’ designs switch from predominantly physical to largely digital and back again, an excellent approach that provides a maximum amount of useful information.

It’s also worth noting how snowbanks are effectively used to seamlessly transition from one section to the next.

3. Create Well-Organized and Helpful Shopping Experiences

More people spending more time at home has created a surge in online shopping. As a result, many online store owners are now feeling the effects of increased competition.

Consumers look for brands they believe they can trust. At the same time, they want their online shopping experiences to be as quick and painless as possible. They look for (and expect) quick and effective product search capabilities, helpful and effective product displays, one-page product descriptions, and the like.

Walgreen’s product page design is especially well-suited for 2021 ecommerce shoppers: 

Everything shoppers usually need to know is presented above-the-fold. They can easily proceed to the next step or scroll down for reviews or additional product specifications. 

BePestControl’s pre-built website uses a similar product design approach: 

In this example, the main selling points are up-front and are kept short and sweet. The shopper can either hit the ‘Add to Cart’ button or look below the button for additional information.

In both examples, a visitor doesn’t have to mull over what step to take next since one of the design objectives is to make the shopping experience as easy and as satisfying as possible.

4. Take Advantage of the Benefits of User-Controlled Video Content

Once upon a time, video content was “the thing” to incorporate in a website. Hero background videos proved to be particularly engaging, and “how-to” videos presented much more useful information than illustrations or blocks of text could.

On the other hand, Auto-play videos, those that started on their own, all too often had a tendency to irritate rather than inform, especially when their content didn’t address a visitor’s immediate concern.

Thanks to Zoom and similar video platforms that came into widespread use in 2020 and to website designs that include video “Play” buttons, users have become much more comfortable with the medium. As an example, Shoppers have been given total control over if or when they want to view a given video. 

This is the design approach Payoneer has taken: 

The white “Pay” button is impossible to miss, and while it is designed to encourage a visitor to watch a testimonial, doing so is completely optional.

The BeOptics pre-built website cleverly slips in a video play option as well: 

In this example, when visitors hover over the “See More” button, it lets them know that they have the option to watch the video if they want to learn more.

5. Trust Builders Should be Non-Negotiable Web Design Elements

There are various ways in which products are organized or showcased in brick and mortar businesses to instill trust. Helpful and friendly staff also contribute to instilling trust.

Some of these trust-builders are easily incorporated into eCommerce designs. Others, though more difficult to fit in, can usually be satisfactorily addressed.

Digital trust builders can include.

  • Logos (familiar, whimsical, innovative, engaging)
  • Portfolios and/or product pages
  • Customer reviews, product ratings, and client testimonials
  • Case studies and product or price comparisons
  • Safety and security seals, e.g., Better Business Bureau, PayPal checkout
  • Charts, graphs, counters, and other data visualization techniques
  • Proof of social, charitable, or community-related actions and contributions

Put, trust-building content will beat hard-sell techniques every time, especially if you would like your customer base to include referred and repeat customers.

Omaze, for example, gives people entries for prizes based on their donations while at the same time highlighting the good things it and its donors have brought about.

To help build trust, the site devotes space to highlighting publications that have featured Omaze and the work it has done and is doing.

Plus, it puts data visualization and non-profit testimonials into play to give visitors an added insight into what is going on behind the scenes: 

As you can see, it doesn’t have to be difficult to incorporate genuine trust-building content into your website designs.

BePortfolio is a great example of how you might go about doing this for a portfolio site, whether it’s your own or a site for a client:

The home page alone has plenty of space for including trust-building content:

  • A satisfied customer counter
  • Product usage case studies and testimonial
  • Portfolio highlights
  • Client and partnership logos

And it can only get better as a visitor moves through the site, but only if you’ve chosen to make that happen.

Have You Started to Take These New Web Design Trends to Heart?

We’re not suggesting that you throw the baby out with the bathwater, but some trends will need to be discarded to enable you to adjust to a new normal. Other 2020 design trends, like minimalism and headline topography, are likely to remain popular for years to come.

New trends that incorporate calming color palettes, image blending, more efficient eCommerce UX designs, user-controlled video, and trust-building elements should give your customers the feeling of comfort and security they will be seeking in 2021.

If you want to implement some or all of these new trends in your 2021 website designs, BeTheme’s 600+ pre-built sites make doing so an easy task.
